It was discovered that a heap-based buffer overflow existed in the FreeType library. If a user were tricked into using a specially crafted font file, a remote attacker could cause FreeType to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2016-10328).
FreeType 2 before 2017-03-24 has an out-of-bounds write caused by a heap-based buffer overflow related to the t1decoderparse_charstrings function in psaux/t1decode.c (CVE-2017-8105).
FreeType 2 before 2017-03-26 has an out-of-bounds write caused by a heap-based buffer overflow related to the t1builderclose_contour function in psaux/psobjs.c (CVE-2017-8287).
